Benefits of technology
The present invention provides a high voltage discharge protective device that can protect RF devices from undergoing high voltage. It has a bare blocking capacitor and a metal conductor between the exposed portion of the blocking capacitor and the circuit board, making it cost-effective and easy to mount on RF devices.
Problems solved by technology
There are a lot of shortcomings to employ the ordinary discharge components or devices for example, high material cost and great dimension resulting in space limitation.
Furthermore, the cost of producing the high voltage discharge protective device is low, and the high voltage discharge protective is miniature to make it easy to be mounted to the RF device.

Embodiment Construction
[0024]The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like reference indicate similar elements. It should be noted that reference to “an” or “one” embodiment in the disclosure are not necessarily to the same embodiment, and such references mean “at least one”.
[0025]FIG. 1 illustrates an embodiment of a high voltage discharge protective device 100. The high voltage discharge protective device 100 can be employed in an RF device,=of the cable television network. The high voltage discharge protective device 100 is arranged at a signal port of the RF device to block DC, couple RF, and protect the RF device from high voltage discharge. The high voltage discharge protective device 100 includes a blocking capacitor 2, a circuit board 1, and a metal conductor 3. The blocking capacitor 2 is fixed to the circuit board 1, and the metal conductor 3 is secured to the circuit board 1 and grounded.

Abstract
A high voltage discharge protective device for an RF device having a signal port, includes a blocking capacitor arranged at the signal port of the RF device, a circuit board for mounting the blocking capacitor, and a metal conductor grounded and partially bare. The blocking capacitor includes a main body and two leads connected to the main body and secured to the circuit board. The bottom portion of the main body is bare to form an exposed portion. The exposed portion is spaced apart from the circuit board to form an interval. The metal conductor is disposed within the interval and corresponds to the exposed portion of the blocking capacitor. When the passing voltage within the blocking capacitor reaches a predetermined value, the exposed portion of the blocking capacitor sparkly discharges to the metal conductor. An RF device is also provided.
Description
BACKGROUND[0001]1. Technical Field[0002]The present disclosure relates to RF (Radio Frequency, RF) devices, and more particularly to an RF device having a high voltage discharge protective function / capability.[0003]2. Description of Related Art[0004]In Broadcasting Industry, to protect the signal port of a RF device from undergoing high voltage, a discharge tube, over-current inductor, and on the like, are employed. With the increment of the market competition in RF transmission equipment (CATV) industry, the transmission equipment needs to be predigest, and cost effective. There are a lot of shortcomings to employ the ordinary discharge components or devices for example, high material cost and great dimension resulting in space limitation.[0005]Therefore, there is a perspective for improvement in the art.SUMMARY[0006]Embodiments of the present invention relate to a high voltage discharge protective device and an RF device.[0007]An embodiment of the high voltage discharge protective...
